Embodiment Construction
[0031] like Figure 1A and Figure 1B As shown, the function of the foldable wheel mechanism for a truck of the present invention is: when the truck is fully loaded, each of the two sets of wheels on both sides of the front, middle and rear is in use; when the truck is empty When loading, the first wheel of the two sets of wheels on both sides of the middle, the first wheel and the last wheel of the two sets of wheels on both sides of the tail are folded to the bottom of the truck. In this way, when the wheel system of the truck is fully loaded, all the wheels can bear the load, and when the truck is empty, the friction loss of the wheel system can be reduced by reducing the number of working wheels, thereby prolonging the service life of the wheel system.
[0032] Below, will refer to Figure 2-4 A foldable wheel mechanism according to an embodiment of the present invention is described, wherein figure 2 A schematic diagram showing the structure of an "L"-shaped connector ...

The invention discloses a foldable wheel mechanism for a heavy truck and a wheel folding method of the foldable wheel mechanism. The foldable wheel mechanism comprises an L-shaped connecting piece, a spherical hinge, a first connecting piece, a second connecting piece and a third connecting piece, wherein one end of the L-shaped connecting piece is connected with a wheel, and the other end of the L-shaped connecting piece is of a spherical shape; the spherical end of the spherical hinge is connected with the other end of the L-shaped connecting piece, and the other end of the spherical hinge is connected with a truck frame through a rotary hinge; one end of the first connecting piece is connected with a rod shaft part of the spherical hinge through a rotary hinge; one end of the second connecting piece is connected with the first connecting piece through a rotary hinge, and the other end of the second connecting piece is connected with the truck frame through a rotary hinge; one end of the third connecting piece is connected with a main body part of the first connecting piece through a rotary hinge, and the other end of the third connecting piece is connected with the truck frame through a rotary hinge; the third connecting piece is provided with a hydraulic device. According to the foldable wheel mechanism, the tire wear of the wheel can be effectively avoided, and the service life is prolonged.
Description
technical field [0001] The invention relates to the field of automobiles, and more particularly, to a foldable wheel mechanism and a wheel folding method thereof, which can stow tires when the automobile is unloaded and reduce tire wear. Background technique [0002] With the modernization and informatization of social development, while the pace of people's life and work is getting faster and faster, the automobile industry has also developed rapidly with the development of the national economy and the comprehensive establishment of the transportation system. The means of transport are favored. As a part of the car, automobile tires are subjected to various complex loads from the road and loading. Tire wear is the fundamental reason for the reduction of tire service life, which also reduces the safety of trucks and increases the cost. In the prior art, all the wheels of the large truck are kept in use, but when the large truck is unloaded, the body weight does not require...
